Had issues with which way locking bars were turning. Tried all combinations...real fix is to have the flats on the capture plate vertical and not horizontal. Another helpful manual moment. Found that I could pop the dog of the lock off and reverse. This gave me a direction that would work, but both locks worked like the front lock...i.e. the key is retained in the lock when it is unlocked. Will need to use two keys at same time to open and close door. Will put two keys on a stretchy cord.
